Someone posted this over on Reddit right when it happened and I apparently saved it. I'm cleaning out my bookmarks and came across it. I hought you'd like to see why it's good news that we found Lemmy.
Edit: I took a screenshot in case it gets deleted.
If you delete comments, they still exist (but are hidden from the public) so reddit can still sell the content/conversation to 3rd parties, eg for training language models. If you edit the comments first, it makes the conversation nonsensical and reddits "product" is less valuable
